Has anyone ever heard of the nub theory to guess the sex? What you's think? Boy or girl xx

girl x

I think its a girl this time x

boy at 21 weeks

This is my second boy, and with my first I found out at 15 weeks so had a scan when I was 18 weeks and then at 22 weeks, and my boys first scans look different from this baby's lol?? I don't think you can judge by nub theory as I've looked on google and seen girls with same shape skull as my 12 week scan lol @maxymosmum xx

@lauren16, god yea you can really see a difference in the skulls! I had a boy first and i knew by his skull shape because it was so sharp and chiselled lol xx

20 week scan xx @maxymosmum

That's my boys 12 week scan xx @maxymosmum

@lauren16, i really hope your right! Ive heard of the skull theory but was reading about the nub theory too and im thinking girl too 🙊 x

Girl 👍🏻 just a guess, as they say girls have more rounder heads xx
